[Preparation of Rubber Accelerator Tetraisobutylthiuram Monosulfide and Its Spectral Analysis]

In the study, rubber accelerator tetraisobutylthiuram monosulfide (TiBTM) was synthesized by two-step method with hydrogen peroxide as oxidant firstly. TiBTM was detected and characterized by FTIR, XRD, TG-DSC. Its micro-structure and intrinsic regularity were revealed. Chemical bond types into TiBTM molecule were revealed by FTIR. TiBTM phase composition and structure were given by crystallographic data from XRD detecting such as cell parameters, crystal face index. The phase composition and qualitative identification of TiBTM structure were completed. Two kinds of information were detected by TG-DSC as quality change and thermal effect. TiBTM phase transition and decomposition temperature were 75.1 and 287.0 ℃ respectively. Uhe decomposition temperature of TiBTM was very high, samples possessing with high purity, without other impurities. It could provided reference with research on rubber vulcanizing and multiple functional properties by TiBTM on rubber vulcanizing machine. This study can provide the basis experimental data on the enterprises to designate the working standard tracing detection of TiBTM industrialized production. The best technological conditions and parameters could be provided for the enterprises to adopt cleaner production process of TiBTM. Performance index of TiBTM was judged. The project of TiBTM industry standard can be declared by the enterprises, written a draft standard.
